i have a 1/4scale chippie, it orginally had the q42 cc in
as i cannot get the q42 to run stable i have deiced to change the engine
now i have some advice to put a 35cc back in it
i was wondering if the ngh38cc fs would be adaqate power or should i up the power to 55cc with rear or pitts, to give me wriggle room
by the way the q42 is free to a good home it runs then dies.
